Having lighting problems

[kman67rsss]

I just got my car back from paint. its a 67 RS/SS camaro. before going for paint everything electrical worked well. the headlight doors worked, directionals etc. anyways, all of a sudden the headlight doors wont open, and when i turn on the headlights the dash lights and taillights go out. they work fine with just the parking lights though. does this sound like a bad headlight switch, ground issue? anything else. thanks for the help
